this post is Not about the value of zcash "token"...

zkSnark is a zcash integration of ethereum.
So...,
"private transactions" is no product anymore, it is a feature.
the zero-knowledge-proof technology within the blockchain space is not a zcash exclusive anymore.

So, the value of zcash has no real world support... !
this value results as an appreciation of this technology as there is huge demand for zero-knowledge transactions and it is useful to reward zcashs developers.
